The given expression is:
+14%5E2+=+13x+%2B+12+

This can be written as:

+14x%5E2+-+13x+-+12+=+0

Using the quadratic formula, we get:

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

x+=+%2813+%2B-+sqrt%28+169-4%2A%2814%29%2A%28-12%29+%29%29%2F%282%2A14%29+


x+=+%2813+%2B-+sqrt%28+169+%2B+672%29+%29%29%2F%2828%29+

x+=+%2813+%2B-+sqrt%28841%29+%29%29%2F%2828%29+

x+=+%2813+%2B+-+29%29+%29%29%2F%2828%29+

+x+=+42%2F28+ OR x+=+-16%2F28
